The research of development status and countermeasures of exercise cardiopulmonary rehabilita-tion in level 2 and above the general hospitals in Chongqing Municipality / 中华医学教育探索杂志

Objective To understand the current development situation and the existing problems and deficiencies of the exercise cardiopulmonary rehabilitation development in Level 2 and above the general hospitals in Chongqing, and to analyze and find out the factors restricting the development of cardiopul-monary rehabilitation in Chongqing, and put forward suggestions for reform and development. Methods Through literature research, field visits and questionnaire survey, the condition of 115 Level Two compre-hensive hospital's rehabilitation and exercise cardiopulmonary rehabilitation development in Chongqing was understood. Among them, 500 questionnaires were sent to 6 hospitals concerned with cardiopulmonary rehabilitation service, and 483 questionnaires were received with 351 valid questionnaires. Epidata3.1 and SPSS 13.0 statistical software were used to gather research data. Results The settings rate of 115 secondary general hospital rehabilitation was 41.7％, while only 6 hospitals carried out cardiac rehabilitation and cardio pulmonary rehabilitation. There were few rehabilitation beds, the basic staffing was inadequate and the medical staff ratio was only 2 to 2.6. Besides, there is a severe shortage of full-time health instructors.Conclusion The clinical sports cardiopulmonary rehabilitation in Chongqing is as following: The construc-tion of hospital related policies is lagging behind, the overall development of rehabilitation therapy is unbal-anced, the development is late and the level of operation is low. While the lack of professional health movement means that instructors and medical staff have cognitive impairment, residents have low accep-tance of sports rehabilitation therapy and there are insufficient pathogens, which are the main factors that restrict the development of cardiopulmonary rehabilitation.

Analysis of cortical lateralization during mental task of geometric figure rotation / 生物医学工程学杂志

Mean Kolmogorov entropy within one second is introduced and is used to analyze and localize the cortical lateralization based on spontaneous EEG and nonlinear dynamics. The results of analysis indicate: The conclusion drawn form the use of this method is almost consistent with that from other methods, but this method is more sensitive to cortical lateralization; this method can identify the differences of cortical lateralization between different brain areas. To analyze and localize cortical lateralization, mean Kolmogorov entropy based on spontaneous EEG is a good method.

A New Method for Monitoring the Status of Central Nervous System during General Anesthesia / 航天医学与医学工程

Objective To investigate the status of central nervous system(CNS)during general anesthesia using a new method of monitor.Methods Eighteen patients during general anesthesia were randomly chosen as the subjects.EEG signals of the patients were recorded as the subject was undergoing a surgical operation.Status of CNS of the patients during general anesthesia was monitored through the changes of Kolmogorov entropy(KE)of the EEG signals.Results Under the same kind of anesthesia measures,though most patients' CNS presented roughly the same status,but important differences were found in individual cases.Some presented depressed CNS status,some presented excited CNS status and others presented epileptic status.Conclusion The same general anesthesia may have different effects on different subjects.KE can reflect the status of the prefrontal cortex during general anesthesia.KE may be a new tool for monitoring the status of CNS during general anesthesia.

Monitoring on Depth of Anesthesia Basing on ? Rhythm Autocorrelation of EEG Signals / 航天医学与医学工程

Objective To explore the relationship between the depth of anesthesia and the autocorrelation of spontaneous EEG signals,and to find a new indicator which is easily calculated and involves fewer channels of ECG.Methods Eighteen patients with a surgical operation on chest or abdomen under general anesthesia served as the subjects.EEG signals of the patients were recorded.Change of ? rhythm of the EEG signal during general anesthesia was investigated by autocorrelation.Results The changes of autocorrelation indicator in channels Fp1-Cz and Fp2-Cz were obvious and consistent with the process of anesthesia;The changes of autocorrelation kcr in the two observed channels were almost synchronous.Conclusion The autocorrelation indicator kcr may be a new idea and a new tool for monitoring depth of anesthesia with fewer channels and the method will find wide prospect of application in clinic and in related scientific research work.
